Did you see the race in Minsk? It was basically rabbitted by Osika at 4:03-04 pace with a much better job than the rabbits at the last three DL meeting I saw. Not to denigrate Kate Grace's achievement but she got very good support from her teammates.
Yes, perfect setup for Kate. Ran the rail the whole race, good conditions, pacing, peaking, etc...Surprised her 1500 p.r. was rather modest.
